Information systems must reflect accurately the business processes that they are designed to support. Faulty understanding of the underlying nature of the business processes is the most frequent reason for the failure of system development projects.

Over the course of hundreds of projects PersonaTEC has refined the SIABA method for quickly and accurately mapping the relationships among information flows and business processes. This method is described in detail in the book Myths and Methods: A Guide to Software Productivity by David T. Fisher, a Senior Consultant at PersonaTEC. The result of the SIABA process is a metadatabase which provides a solid foundation for the design of systems that optimize information flows and maximize organisational efficiency.
